## Summary description

Lightwin 25 Gbit SFP28 LR is a singlemode fiber SFP28 transceiver supporting 25 Gbit/s over LC-Duplex up to 10 km with DDM monitoring. Designed for high-speed links in data centers and carrier networks, it fits SFP28 ports and is RoHS compliant with a 3-year warranty for reliable optical connectivity.

## Long description

Lightwin 25 Gbit SFP28 LR is a single‑mode fiber optic transceiver in an SFP28 form factor that supports data rates up to 25.78 Gbps over LC‑duplex connectors and link distances up to 10 km on standard single‑mode fiber. The module includes a DFB laser transmitter, a PIN photodiode receiver and integrated digital diagnostic monitoring (DDM). It is hot‑pluggable, operates from a single 3.3 V supply and is housed in a metal enclosure to reduce electromagnetic interference.
Advantages
The transceiver provides high‑speed 25 Gbit/s connectivity with low power dissipation (\< 1.5 W) and built‑in dual CDR for reliable serial data recovery. Compliance with the SFF‑8402 SFP28 footprint and LC duplex connector ensures broad compatibility with SFP28 ports in switches and servers. The metal housing and DDM support facilitate stable operation and easy monitoring in data center and carrier environments.
Suitable for
25 Gbit/s uplinks and server interconnects in data centers
Aggregation and edge links in carrier or enterprise networks
Single‑mode fiber runs up to 10 km between sites
Equipment with SFP28 LC‑duplex ports requiring DDM monitoring
When it may not be suitable
This module is designed specifically for single‑mode fiber and LC‑duplex connectors; it is not suitable for multimode fiber or for links that require different connector types such as MPO. It also does not support extended distances beyond 10 km or data rates above the specified 25.78 Gbps.
Key specifications
Maximum data rate: up to 25.78 Gbps
Maximum link distance: up to 10 km on single‑mode fiber (SMF)
Transmitter type: DFB laser
Receiver type: PIN photodiode
Connector: LC duplex
Form factor: SFP28 (hot‑pluggable)
Power supply: single 3.3 V
Power dissipation: \< 1.5 W
Built‑in features: dual CDR, digital diagnostic monitoring (DDM)
Housing: metal enclosure (reduced EMI)
How to use
Insert the SFP28 transceiver into a compatible SFP28 slot on a switch, router or network interface card while the host device is powered on or off (hot‑pluggable). Connect LC‑duplex single‑mode fiber patch cords to the module’s LC connectors, observing correct TX/RX orientation. Verify link status and monitor optical parameters (power, temperature, voltage, bias current) via the DDM interface supported by the host equipment.
What to consider before purchase
Ensure your equipment has SFP28 LC‑duplex ports and supports 25 Gbit/s optics
Confirm single‑mode fiber is installed and that link distances do not exceed 10 km
Check that DDM monitoring is required and supported by your host device if diagnostics are needed
Verify power and thermal conditions in the installation environment for modules with metal housings
Usage recommendations
For reliable performance, use high‑quality single‑mode fiber and clean LC connectors before insertion. Monitor DDM values periodically to detect signal degradation, and use transceivers of the same type and lane speed when configuring 25 Gbit/s links.
